+++ This bug was initially created as a clone of Bug #31256 +++
root@master501:~# /usr/share//ucs-test/51_samba4/35smbclient_auth -f
...
session setup failed: NT_STATUS_IO_TIMEOUT
...
3 of 24 have been successfull.
...
Test failed

The test internally does a
  # ucr set homedir/mount=false
for the duration of the test, but still fails. I tracked it down to some timing problem with samba itself: By default the test does 8 authentication attempts in 5 seconds, repeated 3 times. This is too fast: If I increase it to 6 seconds, it works.
I think Samba has some rate limiting feature to prevent denial-of-service attacks or only has a limited socket.accept()-length.

I rewrote the test do
- be more robust: forkes smbclient don't mess with the tests stdin,stdout,stderr
- easier to read: small functions whith a limited purpose
- easier to follow: prints more progress information
- not use pyexpect: the Python code is shorter
- be cleaner: unused variables removed
- correct: the test is only "careful", because it creates a temporary user
